This Fennel Cod Schnitzel is my pescatarian twist on the classic Austrian schnitzel. Cod cooks quickly, flakes beautifully and stays juicy under a golden panko crust. And unlike veal or chicken, there’s no second-guessing whether it’s cooked through; once it’s browned, it’s ready. The fennel seeds in the crumb add a subtle aniseed note that works really well with fish. Paired with a zingy fennel and apple slaw, it’s a simple but elegant plate that hits salt, crunch, acid and freshness in one go.
If you’re not into fennel, don’t write this Fennel Cod Schnitzel recipe off. You can swap the fennel seed for toasted sesame seeds and get a delicious, nutty variation. You can also use haddock, pollock or even lemon sole instead of cod.

Making the Crispiest Fennel Cod Schnitzel
The beauty of this Fennel Cod Schnitzel lies in its crispness. Each stage affects how cleanly the coating fries and how well it holds. These are the details that separate an average schnitzel from a great one:
- Pat the cod dry: Moisture is the enemy of crispness. Blot the cod fillets with kitchen paper before seasoning or coating. A dry surface helps the flour cling properly and prevents steam from forming under the crust.
- Flatten evenly and gently: Aim for roughly ½ cm thickness. Evenness matters more than precision. When flattening the cod, go gently. Cod is fairly robust raw, but if you bash the fillets too aggressively you’ll tear the flesh and make them hard to handle.
- Crush the fennel seeds: Whole seeds stay harsh and don’t distribute well. Lightly crush them until fragrant but not powdery. This releases their oils so the flavour perfumes the crumb instead of sitting in it.
- Press the crumb firmly: Don’t just coat — press. Push the panko into the fish so it adheres in a single, compact layer. This ensures a clean crust that won’t lift or flake during frying.
- Rest before frying: Once coated, leave the schnitzels to rest for ten minutes while you heat your owl. This allows the crumb to settle and adhere, preventing bare patches or separation in the oil.
- Shallow fry at 180°C” A depth of 2–3cm oil is ideal. At 180°C, the schnitzel should sizzle immediately without smoking. Flip once for even colour and stop when both sides are golden brown.
- Season while hot: Flaky salt needs heat to stick. Sprinkle the schnitzels as soon as they come out of the pan so the salt bonds to the oil and seasons the crust evenly.
What Fennel Brings to the Table
Fennel works on two levels in this Fennel Cod Schnitzel recipe — in the crumb and in the slaw. Crushed seeds in the coating bring warmth and a soft aniseed note that lifts the cod’s mild sweetness. It’s a subtle flavour, more aromatic than pronounced, and frying mellows its sharper edges. The fennel and apple slaw then reinforces that same note in a fresher form, tying the dish together.
If you’re not a fan of fennel seeds, these swaps work really nicely too and bring their own kind of balance:
- Sesame seeds – give a nutty depth and toasty warmth that pairs well with the lightness of the fish.
- Za’atar – adds herbal brightness and a faint citrus tang from the sumac, giving the coating a lift.
- Smoked paprika – brings soft smokiness and gentle warmth without changing the nature of the dish.
- Celery salt – sharpens the flavour slightly and adds savouriness that works well against the sweetness of the slaw.
Each of these alternatives keeps the same idea at heart — contrast and balance, without losing the freshness that makes this Fennel Cod Schnitzel so good.
Why This Fennel Cod Schnitzel Needs a Slaw
This Fennel Cod Schnitzel is rich and crisp, and food like that always needs contrast. The fennel and apple slaw brings exactly that — acidity, crunch and brightness. Fennel gives a clean, fresh bite; apple adds sweetness; vinegar cuts through the richness; and a touch of honey rounds the dressing without making it too sweet. It’s the sharp, clean side that cuts through the schnitzel and resets your palate between bites. Don’t skip it. Make it first and let it sit while you fry — the salt will draw out moisture and form a light, natural dressing.
If the slaw looks dry at first, don’t worry. That’s normal. As it rests, the sliced fennel and apple soften slightly, and the salt pulls out just enough liquid to create a clean, tangy coating. Everything stays crisp but properly dressed — fresh enough to lift the whole plate.
Storage and Reheating
This Fennel Cod Schnitzel is always best, but leftovers still hold up well.
- Fridge: Store the cooled schnitzels in an airtight container for up to 2 days.
- Reheat: Place in a 180°C oven for 8–10 minutes to re-crisp.
- Slaw: Best eaten on the day, but fine in the fridge for 24 hours.
Frequently Asked Questions
Can I prep the schnitzels in advance?
Yes. You can breadcrumb the fish ahead of time to make frying quicker. To stop the coating from softening, store the schnitzels buried in extra panko, with extra crumbs packed above and below each fillet, then refrigerate for up to 24 hours. Bring them to room temperature before frying so they cook evenly.
Can I air fry or bake?
Technically yes, but it’s not ideal. This recipe was developed for shallow frying because that method gives the most even colour and crispness. Air fryers and ovens struggle to deliver the same result — panko needs fat for proper browning and flavour. Even if you generously spray the fillets with oil, the fish will overcook before the crumbs turn golden. So yes, you can air fry it if you absolutely mist, but shallow frying is definitely the best option here.
Do I need a thermometer?
It helps, but it isn’t essential. If a breadcrumb sizzles instantly on contact, the oil is ready. That said, a thermometer is one of the most useful tools to have in the kitchen — it takes out the guesswork and costs very little. This is the thermometer I use.

I’ve been sharing lots of delicious fish recipes on my Instagram and TikTok in a series I’ve called Fantastic Fish. If you love this Fennel Cod Schnitzel recipe, here are some other delicious fish recipes that you might enjoy.
- Fish Katsu Curry: Swapping chicken for fish brings a new lightness and crispiness to the dish. It gets an extra layer of depth from caramelised onions – a small detail that makes all the difference.
- Coconut-Crusted Thai Curry Sea Bass: If you’re a fan of Thai flavours, you’re going to love this one. The fish is marinated in Thai red curry paste, before being encased in a coconut crust and fried to golden perfection.
- Coconut Milk Poached Fish: Inspired by Southeast Asian flavours, this dish features tender, flaky white fish, gently cooked in a fragrant, aromatic coconut broth.
- Fish and Prawn Toast: A lighter, more affordable twist on the Chinese takeaway classic. Instead of all prawn, the filling is mostly flaky white fish with just a little prawn for texture. The fish keeps it delicate and fresh, while the prawn adds that springy bite you expect.
- Curried Fish Burger: My take on a classic fried fish sandwich, with bold Indian flavours running through every layer. The fish is coated in a spiced beer batter that fries to a golden, shatteringly crisp crust. The cucumber raita and coriander chutney provide balance: one cool and creamy, the other sharp with heat and herbs. Tucked into a toasted brioche bun, the result is indulgent yet bright
Fennel Cod Schnitzel with Fennel and Apple Slaw
This Fennel Cod Schnitzel is my pescatarian twist on the classic Austrian/German schnitzel. The fennel seeds in the crumb add a subtle aniseed note that works really well with fish. That said, if you aren’t a fennel fan, you can substitute it for toasted sesame seeds for a nutty alternative.
- Prep Time: 20 minutes
- Total Time: 45 minutes
- Yield: 4 1x
Ingredients
For the fennel and apple slaw:
- 1 tbsp apple cider vinegar
- 1 tbsp extra-virgin olive oil
- 1 tsp runny honey
- 1 fennel bulb, very thinly sliced
- 1 pink lady apple (or any sweet & crisp variety), cut into matchsticks
- ½ shallot or ¼ onion, very thinly sliced
- small handful flat-leaf parsley, finely chopped
For the fennel cod schnitzel:
- 1–2 tbsp fennel seeds (use the higher end of you love fennel and want a pronounced flavour)
- 400g panko breadcrumbs
- 120g plain flour
- 4 eggs, beaten
- 4 skinless boneless cod fillets (approx. 125g each)
- vegetable oil, for shallow frying
Instructions
- Whisk the vinegar, olive oil and honey in a large bowl. Add the fennel, apple and shallot, season with salt and black pepper and toss to coat.
- Add the parsley and toss again, then refrigerate until needed. The slaw will look underdressed at first but as it rests the salt will draw out moisture, creating a fresh, tangy dressing.
- Lightly crush the fennel seeds in a mortar and pestle until coarsely ground but not fully a powder. Tip into a shallow tray and mix with the panko.
- Put the flour into a shallow bowl and season with salt and pepper. Beat the eggs in another shallow bowl.
- Pat the cod fillets dry. Lay a large piece of greaseproof paper or cling film on your work surface and fold it in half. Place one cod fillet inside and gently bash it out to around ½ cm thick using a meat mallet, rolling pin or frying pan. Repeat with the remaining fillets. Season both sides with salt.
- Carefully coat each fillet in flour, shaking off the excess. Dip into the beaten egg, let the excess drip away, then press firmly into the fennel panko mixture until completely coated on both sides.
- Heat your oven to 140°C / 120°C fan. Set a wire rack in a large baking tray.
- Fill a high-sided frying pan or wide pot with 2 to 3cm vegetable oil and heat to 180°C. If you don’t have a thermometer, the oil is ready when a breadcrumb sizzles immediately on contact.
- Fry the schnitzels in batches for 2 minutes per side, or until golden brown on each side. Transfer to the wire rack and sprinkle with flaky salt. Keep warm in the oven while you fry the remaining schnitzels.
- Serve hot with the fennel and apple slaw alongside.
